@am am 2er-1am @Gr-P1? a suitable pulley 5 and the worm shaft 4: is in gear with another shaft 1' by means of gears 6, 6. A clutch 7 is mounted upon the main shaft 1 for connecting and disconnecting the 'pulley wheel 5 with the shaft for rotating the rods 1, the shaft being shifted by means of a lever 8.

The gelatin hopper B is provided at one end with a plurality of openings 9 in which the screws 2 operate, and connected with the bottom of the screw chambers are brass tubes 10, 10. .The gelatin is fed from the hopper B into a receiving chamber 11 and the quantity of gelatin which is discharged into the receiving chamber 11 isA separated from the contents in the hopper B by means of a knife 12. A piston 13 is received in the receiving chamber 11 for causing the contents of the chamber to be forced to the feeding screws whereby the gelatin will be fed by the screws into the tubes 10, 10.

The blade 12 and the plunger piston 13 are actuated by compressed air. In Figs. 5, G and 7 I have disclosed these parts more in detail and by reference to Fig. 5 it will be seen that the blade 12 is provided with a piston rod 11 which extends into a cylinder l the cylinder: 15

15. A valve 16 is connected to one end of is an inlet pipe 17 through which air is conducted from any suitable source, not shown, to 'the cylinder upon the actuation ofthe rod 1S. The rod 18 operates the valve 16 for admitting air from the pipe 17 into the cylinder 15 for causing the blade to move across the bottom of the hopper B for cutting the gelatin which has been discharged into the receiving chamber 11 and preventthe gelatin from passing into the receiving` chamber.

The plunger piston 13 is provided with the piston rods 19 which extend into the cylinder 20. The piston rod is provided with a piston 21 which is actuated by compressed air which isadmitted to the pipe 22 through a valve 23, the valve 23 being actuated by means of a rod 24 for causing the piston 2l to be moved for forcing the plunger 13 against the gelatin and forcing the gelatin to the feeding screws n. Vhen the l-:ni'l'e or blade 12 is moved practically the limit of its stroke, a trip 25 carried by the slide engages an arm 26 on the rod 18 forcing the rod to be actuated and thereby turning the valve 1G and allowing the air to escape Athrough the pipe 27. A trip 28 carried by the piston rod 19 will engage an arm 29. v

`When the piston plunger practically the limit of its stroke, it causes the rod 2-1A to be actuated for the purpose of operating the valve 23 to allow the air to escape from the casing through a pipe 30. When both the knife and the plunger have and connected to the valvesI 13 is moved completed their stroke and the gelatin has been fed to the screws and itis desired to admit an additional quantity of gelatin to be discharged into the chamber 11, the rod 31 is actuated for operating the valve 32 which is connected with an air supply by a pipe 33 and which valve is connected to a cylinder 15 whereby air is admitted in front of the piston in the cylinder, causing the blade to be moved rearwardly, and during its movement the blade will strike a projection 3st on the rod 31 for actuating the rod whereby the valve will be turned and allow the air in the casing to be discharged through a pipe The plunger 13 is also returning to its rearmost position and the rod 36 is connected to a valve 37. This valve 37 is connected to the cylinder 20 and connected to the valve is an air supply pipe 38 whereby the air is admitted to the cylinder 2O and in front of the piston 24; for causing the piston to move through the cylin'der for drawing the piston plunger 13 rearwardly. A projection 39 on the piston plunger 13 engages an arm 40 on the rod 36 4 which operates the rod for causing the valve 37 to'be actuated to permit of air in the cylinder 2O vto escape through a pipe 41.

, Mounted between 'the uprights A is a shuttle carrier C. The shuttle carrier is provided with.J a shaft 42 which extends 'through with elongated slots 13. Rack bars 44 are mounted in slots 45 of the uprights and meshing with the teeth of the rack bar are gear wheels 116, the gear wheels 46 being mounted upon the shaft 12. The shuttle carrier C has mounted thereon a shuttle E such as shown in Fig. 8 in which paper cartridges or shells are placed which shells are fed onto the brass tubes 10, throughwhieh the gelatin is discharged by-the screws 2. The shaft l2 has mounted thereon a lever the uprights which are provided.

L17 which is provided at one end with 'ilk the shells L19 into a position so that they will L 418 which can be adjusted along the receive the brass tubes 10 within an inch 4 of the bottom of the shells. The gelatinis now fed into the tubes, the clutch 7 having been thrown into engagement with the puly' ley '5 thereby transmitting `power A y to the rods, causing the screws 2,to rotate. The

gelatin is fed through the tubes 10 and as it passes through the tubes into the shells 49 the shellsand carriers C are gradually i descending ,ormoving away from the tubes.

The descent of the carrier is governed by the position, of the weight 48 upon thelever 47, that is, the position of the weightA will govern the back pressure that is exerted against the downward movement of. the shells and regulates the manner of packing ing the carrier to a. posrtion whereby thel shells can be removed from the carrier.
